采用文献资料、访谈调查、数理统计和逻辑分析等方法,对我国职业篮球联赛——CBA联赛13年发展过程中影响竞赛质量主导因素——球队、教练员、队员和外援的发展变化历程进行分析,将对提高联赛水平和质量具有重要的指导意义。结果表明:CBA联赛13年发展过程中,球队数量保持稳定增长,国内球员平均身高和体重呈稳定增长趋势,年龄结构趋向年轻化,引进外援整体水平较高,教练员团队逐渐壮大,一批优秀的年轻教练员逐渐成熟,聘请的外籍教练员普遍水平较高,但整体效果不佳。  相似文献

This study was undertaken to evaluate the role of serum neuron specific enolase (NSE) in prediction of disability and neurological worsening in hypertensive ischemic cerebrovascular stroke. 80 hypertensive ischemic stroke patients diagnosed by a neurologist as per WHO definition along with radiological findings suggestive of cerebrovascular stroke and differentiating from hemorrhagic stroke and 60 controls having essential hypertension coming to hospital because of regular checkup or headache but with no neurological disease were included in the study. Neurological disability was assessed by NIHSS at the time of admission (within 72 h from the onset of stroke) and on 7th day after admission and cases were categorized into mild, moderate and severe disability. Venous blood samples were drawn within 72 h from the onset of symptoms. The samples were processed as per the laboratory protocol. The serum NSE samples were analyzed using an enzyme immunoassay based on the sandwich technique. We observed raised serum NSE in hypertensive ischemic stroke (17.4 ± 5.4 ng/ml) with significant association between different hypertensive groups than in hypertensive controls (9.1 ± 0.75 ng/ml). Greater degree of disability was observed in hypertensive stroke patients with raised serum NSE and hypertensive patients with mean serum NSE level of 22.9 ± 3.6 ng/ml and dyslipidemia had greater probability of neurological worsening as compared to those with mean serum NSE level of 12.7 ± 1.2 ng/ml. Serum NSE levels can serve as a peripheral indicator of neuronal damage and assist in the prediction of disability and clinical outcome in hypertensive cerebrovascular ischemic stroke patients.  相似文献

Effect of irbesartan, an angiotensin II receptor antagonist, was studied in streptozotocin (STZ) induced diabetic nephropathy. Polyuria, proteinuria, blood urea, creatinine clearance, and urinary electrolytes were determined to assess kidney damage. There was a significant increase in urine volume, urinary protein and blood urea in STZ induced diabetic rats. On the other hand, irbesartan treatment resulted in a significant reduction in urinary protein and blood urea in these rats. Irbesartan treatment also improved creatinine clearance and exhibited a natriuretic effect in these animals. Results suggest that irbesartan treatment ameliorate STZ induced diabetic nephropathic changes, in rats.  相似文献

India with a current student population of around 4 million in its universities and colleges is the third largest system in the world after USA and USSR. The unprecedented expansion of higher education in India, which took place in the last four decades, has, however, been extremely uneven and resulted in the neglect of quality, research and managements aspects. The universities and colleges function much below their optimal levels and fail even to fulfil their minimum and basic tasks such as making admissions, completing teaching, conducting examinations, declaring results and awarding degrees on time. The very credibility of the university system stands eroded.Increasing government control, extra-constitutional pressures in their governance, appointment and dismissal of Vice-Chancellors on political considerations and drift of the academic community from serious academic pursuits have undermined the autonomy of the universities. The paper attempts to analyse from macro-micro angles the causes for the decay of the university system.The National Policy on Education-1986 aims at radical reorganisation of higher education to bring about dynamism in the system through multi-pronged strategies and programmes and structural reforms. Policy interventions have, however, failed to create much impact. The paper brings forth some of the important issues vital to the governance of the universities and highlights the need for a collective endeavour of teachers, students, educational administrators and government and rigorous system of performance audit to bring dynamism into the system.  相似文献

The antidyslipidemic activity of Ocimum sanctum leaf extract was studied in streptozotocin induced diabetic rats. In this model, there was significant increase in plasma markers of diabetic-dyslipidemia following diminution of lipid metabolizing enzymes. Oral administration of leaf extract (500 mg/kg b.w.p.o.) for 15 days resulted in significant decrease in diabetogenic and dyslipidemia parameters; namely blood glucose, glycosylated hemoglobin, lipid peroxide, free fatty acids, small dense low density lipoprotein, lipid and protein components of plasma lipoproteins, adipose and liver. The regulation of lipids was accompanied by stimulation of postheparin lipolytic activity, reactivation of lecithin cholesterol acyl transferase and hepatic lipoprotein lipase enzymes. The results of the present study demonstrated antidyslipidemic and antioxidant activities in leaf extract of O. sanctum which could be used in prevention of diabetic-dyslipidemia and related complications.  相似文献
